With respect to array types, does that limit you to a certain amount, unlike plain old type types where you can add to the list ad infinitum?
The answer is no. Technically, you cannot create an infinite number of objects due to memory limitations. For improved memory management, you should set a limit to the number of objects created. You could always use a very large number.Type Arrays are documented in the Blitz Basic Language Reference: Custom types. Another possibility is to use the Object/Handle Functions. However, these functions are not documented.
